Charting the Unknown:
the Hunt for Dark Matter Continues

For thousands of years, the human mind struggles to
answer a simple question: what is the universe made of? The majority of
what composes our universe, dark matter and dark energy, are just
mysteries. Undoubtedly, dark matter is one of the most interesting
fundamental puzzles of our universe. While we have accumulated sufficient
cosmological evidence supporting its existence, the character of the dark
matter particle is still unknown. The widely successful theory of
elementary particles, the standard model, is incapable of providing an
interpretation of the dark matter puzzle, pressing towards new theories. A
myriad of models have been proposed, the majority of which introduce a
single dark matter candidate for simplicity. Though they provide testable
hypotheses at various experiments, little attempt has been made beyond
single-candidate dark matter. In this talk, we go beyond single-candidate
dark matter by focusing on two-component dark matter candidates.
Surprisingly, their phenomenology is very different from that of
single-candidate, providing a new avenue for dark matter experiments. In
particular, we examine a novel thermal dark matter scenario where
present-day annihilation of dark matter in the galactic center or in the
Sun may produce subdominant but detectable boosted stable particles via
neutral-current like interactions. Detailed detection prospects are studied
at deep neutrino experiments and traditional direct detection experiments.
We stress that the extension of dark matter models with more than one
candidate beyond the minimal dark matter model opens up a new window for
various experiments. Such a theoretical investigation and multiple
experimental probes will advance our knowledge about dark matter and
perhaps lead to its discovery in the near future.
